Findings: CT of the neck demonstrates an air-filled lesion adjacent to the proximal esophagus with a questionable connection between the two lumens. Subsequent evaluation of the hypopharynx and upper esophagus demonstrates a large outpouching from the left side of the cervical esophogus originating just inferior to the cricopharyngeus muscle.

MPX1297_synpic19926: Fluoroscopic lateral image of the esophagus demonstrates a large divertculum overlying the proximal esophagus (arrowhead). Lateral view verifies that the lesion arises just inferior to the impression made by the cricopharyngeus muscle (arrow), diagnostic of a Killian-Jamieson diverticulum.
